Background: Mutations in KRAS and BRAF genes are prevalent in colorectal cancer (CRC), which strikingly promote tumorigenesis and lead to poor response to a variety of treatments including immunotherapy by activating the MAPK/ERK pathway. Thus, there is an urgent need to discover effective therapeutic targets and strategies.
Methods: CRISPR-Cas9 lentiviral knockout library was used to screen the suppressors of anti-PD1 immunotherapy.
Nonhealing chronic wounds are intractable clinical complications of diabetes and are characterized by high protease activity, severe oxidative stress and sustained inflammatory response. In this case, the development of functional hydrogel dressings to modulate the immune microenvironment is a well-known strategy, where the precise stimuli-responsive and spatiotemporally controlled release of bioactive molecules remains a huge challenge. Herein, we developed responsive hydrogels with self-regulated bioactive molecule release based on the protease activity in diabetic wound sites, to serve as a smart immune microenvironment modulator for accelerating wound healing.

However, there is still a lack of evidence regarding the association between phthalates and overall survival (OS) in advanced high-grade serous ovarian cancer (HGSOC). This study investigated the relationship between urinary phthalate metabolites and OS in patients with HGSOC using a nested case-control study within the Ovarian Cancer Follow-Up Study.
View Article and Find Full Text PDFBackground: Dietary factors impact systemic inflammation, which not only correlates with poorer outcomes in patients with ovarian cancer (OC) but also promotes cancer development through increased cell division, genetic alterations, and malignant transformation of epithelial cells at inflammatory sites. However, evidence between dietary inflammatory patterns and OC survival remains sparse.
Objective: The aim of this study was to examine associations between pre- and post-diagnosis dietary inflammatory patterns, including their changes, and overall survival (OS).
Androgenetic alopecia (AGA) continues to pose a significant challenge due to the paucity of effective therapeutic options. Upon lysis, platelet-rich plasma (PRP) releases numerous growth factors (GFs), which facilitate tissue reconstruction and hair regeneration. However, concerns such as infection, bleeding, local erythema, and patient anxiety associated with injections have substantially diminished patient acceptance.

Exploring the influence of farmer' survival situation on their willingness to convert cultivated land to non-grain land can provide theoretical support for formulating control policies for NGC of cultivated land. Based on the data obtained from 650 questionnaires in Henan Province and using the SOR model as the theoretical basis, this study explored the impact mechanism of the survival situations of two types of farmers, namely, those with agricultural livelihoods (AL) and those with nonagricultural livelihoods (NL), on their willingness to convert farmland into non-grain land through the use of structural equation models.

Recent studies have emphasized the modification of Insoluble Dietary Fiber (IDF) to enhance its physicochemical properties and functional performance. This study systematically examined the effects of ultrasonic treatment, microwave irradiation, high-temperature and high-pressure processing, and screw extrusion on the physicochemical characteristics, in vitro antioxidant activity, and adsorption capacities of High-Purity Insoluble Dietary Fiber (HPIDF) derived from black bean residues. Although these physical modifications did not alter the functional group composition or crystalline structure of HPIDF, they significantly enhanced its porosity, water-holding capacity (WHC), oil-holding capacity (OHC), and adsorption capacities for glucose, cholesterol, bile salts, and metal ions.
